The Campaign for Nuclear Disarmament (CND) was founded 60 years ago. In this photograph, US civil rights campaigner Bayard Rustin is addressing a crowd in Trafalgar Square on Easter weekend 1958. They are about to begin the iconic 52-mile march from London to Aldermaston Atomic Weapons Research Establishment.

To commemorate the anniversary, the CND is holding events across the UK, including film screenings and a tour of a sculpture of the CND symbol – the internationally recognized peace sign.

Nuclear weapons are back in the spotlight for the first time since the 1980s. The International Campaign to Abolish Nuclear Weapons won the Nobel Peace Prize in 2017 and a new Treaty on the Prohibition of Nuclear Weapons was passed last July. While Iran signed a deal limiting its nuclear energy programme, the United States and North Korea have continued threatening each other with nuclear war.
